Was outside messing with this motor tonight, was going to pull the head off to check the differences with another head. I rolled the motor over with the plug out ans it was still hard to roll it over which kind of puzzled me at first. Pulled the shroud off of the motor and it looks pretty clean under it.
Looks to have a new coil on the motor and whomever installed it didn't gap the coild and flywheel, just let the coil drop until touching and tightened it down. It was dragging on the flywheel pretty hard, so I loosened the coil and and it rolled over just fine then. As I was rolling the motor over I heard a "Whistling" sound coming from the splined shaft, got to looking and there is a small holw at the bottom of the shaft that vents the crank case. Guess this shoots the using this side cover with a different crank.
